Editor to share with you how to build OPENSTACK open source virtualization KVM deployment, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Introduce the environment.

Physical machine: an old HP server, but it is still enough for learning

Operating system: WIN2008

Virtualization: VMware ®Workstation 12 Pro

Network card: network port 1 access router LAN1

CPU must support virtualization technology, set to startup in BIOS

At present, most server basic desktop computers handle the startup state

We need to use virtual machines first, and then use virtualization in virtual machines, that is, nested virtualization.

VMware nested Virtualization

Product: Workstation,Player,ESXi

Support: ESXi,Hyper-V,KVM,Xen

I use Workstation+contos7.3 here.

Installation of KVM begins

The initial installation is as simple as installing CentOS. Check the installation software such as

Assign an IP to this mainframe.

When equipped with IP, you can log in through Xshell.

There is a problem here. It is stuck in license information after reboot.

If license information (license not accepted) appears, that means you need to agree to the license information, enter 1-enter-2-enter-c-enter-c-enter. It can be solved.

Build the local yum warehouse CD source and install the software package

[root@localhost ~] # cd / etc/yum.repos.d

[root@localhost yum.repos.d] # ls

CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo

CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo

[root@localhost yum.repos.d] # mkdir bak

[root@localhost yum.repos.d] # mv C* bak/

[root@localhost yum.repos.d] # vim local.repo

[root@localhost yum.repos.d] # cat local.repo

[local]

Name=local

Baseurl= file:///media/cdrom/

Gpgcheck=0

Enabled=1

[root@localhost media] # mount / dev/sr0 / media/cdrom/

Mount: / dev/sr0 write protection, which will be mounted as read-only

[root@localhost yum.repos.d] # yum-y clean all

Loaded plug-ins: fastestmirror, langpacks

Cleaning software source: local

Cleaning up everything

[root@localhost yum.repos.d] # yum makecache

Loaded plug-ins: fastestmirror, langpacks

Local | 3.6 kB 00:00

(1ap4): local/group_gz | 155 kB 00:00

(2ache 4): local/primary_db | 3.0 MB 00:00

(3x4): local/filelists_db | 3.0 MB 00:00

(4ache 4): local/other_db | 1.3 MB 00:00

Determining fastest mirrors

Metadata cache has been established

[root@localhost yum.repos.d] #

We also need to add the following software packages

# yum installation package group

[root@localhost ~] # yum-y group install virtualization-client

[root@localhost ~] # yum-y group install gnome-desktop

KVM remote management

[root@localhost ~] # which virsh # View virtual machine management commands

/ usr/bin/virsh

[root@localhost ~] # virsh list-- all # View all virtual machines

Id name status

[root@localhost ~] # startx switches to graphical interface mode

Select Application in the upper left corner under the graphical interface to open the management tool of KVM

Two ways of remote Management of KVM

We usually need to remotely manage the KVM environment at work. The desktop mode is not visible in SSH mode.

1. VNC graphics

In this way, the corresponding applications need to be installed on both the server and the client.

2. SSH graphical display

Windows installs the software x-manager. Then xshell software turns on X11 forwarding

Then after we connect to the virtual machine, enter virt-manager to show the following figure

At this point, the KVM and management tools have been built.

Create a virtual machine
